St. Olaf Choir

The St. Olaf Choir is a premier a cappella choir based in Northfield, Minnesota. Founded in 1912 by Norwegian immigrant F. Melius Christiansen, the choir has been influential to other church and college choirs for its performance of unaccompanied sacred music. Conducted since 1990 by Anton Armstrong, there have been four conductors in the choir's 114 year history.
